1946 ad for Kodak High-Speed [Movie] Camera, Type III.<\/p><\/div>Toronto<\/strong>. Most of you know how slow motion video\/movie works, but for the few who do not, the idea is simple. Movies are shown at 24 frames per second, up from the slower frame rate for older films.<\/p>\n

Video uess a slightly faster 30 frames per second. Persistence in the human brain is the secret to thinking you see smooth motion. For slow motion, the images are recorded at a faster frame rate and projected at the ‘normal frame rate’.<\/p>\n

A November, 1946 advertisement by Kodak in the American Cinematographer announced the use of its high speed camera (High-Speed Camera, Type III) to create slow motion movies of extremely fast events – ‘too fast for the human eye to register’. This camera can take 1,000 to “3,000 pictures[frames] in one second”. This means anything photographed is shown slowed down ‘nearly 200- fold’.<\/p>\n
